Calculator inputs stay in your browser

All numerical inputs (D, S, C, i, lead time, sigma, service level, tier prices and breakpoints) entered into the calculators are computed client-side in your browser. They are not transmitted to a server. We do not log, store, or aggregate them. Closing the browser tab destroys the inputs.

Shareable links use query strings

Where the calculators support a shareable URL, the inputs are encoded into the URL query string. A CFO opening the link sees the same numbers because they are in the URL itself, not on our server. If you don’t want the inputs in the URL, copy the screenshot instead of the link.

Analytics

The site uses standard hosting-platform request logs and Google Analytics for anonymised page-view counts. No personally-identifiable information is collected beyond what your browser passes by default (IP, user-agent string, referrer).
